SMALL-ABM.

Application led J' une 15, 1915.

According to my invention I provide av block capable of a sliding motionin a recess in the front face oi the body of the small arm, the saidblock carrying in a hole or holes the loose striker or strikers of theaction. The sliding motion of the said block may be effected bytheturning of the ordinary top lever or other convenient means may beemplo-yed for effecting the requisite motions of the sliding block. lTherear end of the barrel or barrels has one or more hook shaped parts orprojections which on the closing of the barrel or barrels take intorecesses between the sliding block and the sides of the recess in thefront face of the body hereinbefore referred to, the sliding blockhaving corresponding hook shaped parts or projections capable ofengaging with the said hook shaped parts or projections on the rear endof the barrel or barrels when the latter are closed.

On the closing of the barrel or barrels the top lever or other operatingmeans is turned so as to eii'ect the sliding of the block carrying theloose striker or strikers and eiiect the engagement of the hook shapedparts or projections of the block with those on the barrel or barrelswhereby a very efficient fastening of the gun results.

Where the motion of the sliding block is effected by the turning of thetop lever the turning movement of the lever may be transmitted to theblock through a slide with a notch in which an arm on the lower end oi'the top lever spindle engages, the said slide eliecting the turning of abell crank lever the end of one of the arms of which takes into a recessin the rear face of the sliding block.

I will further describe my invention in its application to a doublebarrel drop down small arm of the type commonly known as Specificationof Letters Patent.

an funder and over gun in connection with which it is especially useful.

Figure 1 of the accompanying drawings represents partly in sideelevation and partly in section so much of an under and over guncontaining the improvements con! stituting my invention as is necessaryto the understanding thereof, the gun being represented closed in fulllines and indicated in its open position in dotted lines. Fig. 2 is a.section on the line 2-2 Fig. 1 with the sliding block in its lowered orunfastening position. Fig. 3 is a side elevation partly in section. Fig.4c is an inverted plan view of the underside of a part of the gun with-4the fixing plate of the trigger guard removed. Fig. 5 is a cross sectiontaken on the dotted line 5 5 Fig. 3 looking in the direction of thearrow in Fig. 8, the lock carrying plates being omitted. Figs. 6 ton 13,both inclusive, are detail views herein-Y after particularly described.Figs. 14, 15 and 16 illustrate a modification of my inventionhereinafter described.

The same letters of reference indicate theV same parts in the severalfigures of the drawings.

a is the body of the gun having in its front face the somewhat largerecess a1 (best seen in Figs. 6 and 7 which are respec- V tively a frontelevation and plan of a portion of the body a), the said recess alaccommodating the block b shown detached in Figs. 8, 9 and 10, Fig. 8being a front elevation of the block, Fig. 9 a side or edge view of thesame and Fig. 10 a sectional plan, the section being taken in a planeindicated by the dotted lines 10-10 in Figs. 8 and 9.

The slide block b carries the loose strikers o, c which are inclinedboth to the vertical and horizontal, that is to say, the striker for theover barrel kis downwardly and outwardly inclined and the striker forthe un-l der barrel is upwardly and outwardly inclined as is usual, aswill be best understood by reference to Figs. 9 and 10. The said blockZ) is retained in the recess al of the body a by flanges Z22, b2 on therear side edges of the block engaging grooves a2, a2 at the inner end ofthe recess al, see Fig. 7.

The rear end of each of the barrels d is provided with an undercutarch-like extension all and with hook shaped parts or projections d2, Z3with which the parts b3, b, b respectively of the block l) are made toengage by the sliding of the said block upward from the positionrepresented in F ig. 2 to the position represented in Figs. 1 and 3 forfastening the barrels d Vin -the --elosed position.

The motion of the block b is effectedby the turning of the ordinary toplever e Which is securedto the inclined spindle f'indicated in dottedlines in Figs` and 5, which spindle has on its lower end a cam orprojection f2 (see Fig. 4). The; said cam engages With projectionsgonfthe sliding-bolt g-shown .separately in lplanofunderside in Fig. 11,`which,nvhen inthe fastening position engages Withnotches in the lumps7L, i onthe underside of theunderrbarrel. lnto holer g1 .in the rear end kof the sliding bolt g the -nearly vertical arm v 701` of a bellcrank'lever c1,7e2, 7a2 (shown detached in Figs. ,12 and 13) depend-s,the freeends offthelhorizontal Y varms k2, 7a2 v projecting into andengaging With notches orrecesses in the rear face of theslidin-g block?)as is best seen in 8.

4I Wishit to be understood that I do not limit lmyself .to anyparticular :means for giving -the vsliding block the .slight up andvdown motion to -eect the lfastening or lun- -gastening .ofithe barrelsand in the arrangementrFigs. 14, 15 and 16 Ihave represented a -pin Zgprojection or thelilre) engagingwith .an inclined channel, or groove???Jinthe rear {ace of the block b, the pin AZ Aprojecting lthrough aslet/min thebody asis best seen in Fig. 15 in ,which the sliding blockis .omitted The said pin Z is inene With a ring or lcollar which itsasquare on the under Vside of the bush of the top `lever` e.
